I would call attention to the fact that Latzel has considered it as 

 probably identical with Trachyjulus Peters, and has given preference to 

 the latter name, although it was given nearly twenty years afterwards. 



In this paper I have considered Acanthiulus as distinct from Trachy- 

 julus. My reasons for this may be found in the following characters 

 which I have culled from Gervais's descriptions and figures of A. blain- 

 villii. 



Ocelli in more than one series; antennae resembling that of Cambala; 

 first and last segments smooth; other segments striate beneath and 

 armed above with eight rows of tubercles, eight on each segment; also 

 a median dorsal series of indistinct tubercles. 



Sides of first segment produced backwards (male?).

1814. — Iulides Leach. Trans Linn. Soc, 376 {in part). 



1842. — CraspedosomadcB Gray. Todd's Cyclop, of Anat. and Phys., in, 546 {in part). 



1847. — Ghordeumiden Koch. Syst. Myr., 49 and 119.

1884. — Chordeumidw Latzel. Myr. Ost.-Ungar. Monarch., II, 171. 



According to the synonymy given above this family should be called 

 Craspedosomidoe and not Ohordeumidce. 

 Gray's and not Koch's name should be employed. 



16. Chordeuma. 



1847. — Chordeuma Koch. Syst. Myr., 51 and 124 (sylvestre). 



1872. — Trichopetalum Harger. Anier. Journ. Sci. and Arts, 117 (in part; iulioides). 

 1884. — Lwriulus Berlese. Acari, Myr. et Scorp ital., Fasc, xn, 6 (inermis = C. 

 sylvestre). 



I agree with Dr. Latzel in considering the Trichopetalum iulioides 

 Harger as belonging to the genus Chordeuma; although there is some 

 probability that it may be the young of some Campodes. Lceriulus Ber- 

 lese, which was placed by him in the Lysiopetalidw is a member of the 

 Craspedosomidce, and is also identical with Chordeuma. 



17. Campodes. 



1847. — Campodes Koch. Syst. Myr., 51 and 126 (flavicornis = fusicomis). 

 1869. — Pseudotremia Cope. Proe. Amer. Philos. Soc, 180 (in part; vudii = C. flavi- 

 cornis). 

 1883. — Cryptotrichus Packard. Proe. Amer. Philos. Soc, 189 (Spirostreptus ccesioan- 

 nulatus Wood = C. flavicornis). 



Campodes Koch has always been overlooked by American authors, 

 as, in fact, have been nearly all the works of Koch. The result has been 

 the description of several genera that are identical with earlier names 

 of his. In the above synonomy I have included Pseudotremia Cope as 

 forming a part of Campodes, while Cryptotrichus Packard is also iden- 

 tical with the latter.
